The picture, above, is an old one of me (after a long day), surrounded by models of polymorphs of
I am a Senior Research Associate for
Inorganic Chemistry here in the department providing support for the
department's X-ray instrumentation. I work closely with
Dr Jeremy Cockcroft
on wide applications of Powder X-Ray Diffraction (PXRD)
and the development of PXRD equipment. This includes two
Stoe StadiP transmission geometry systems, one with
copper radiation, one with molybdenum.
We have added a Cryojet to the copper for low temperature data collection while
the molydenum source has a dedicated furnace (to 900°C)
Stoe StadiP (Cu) and Siemens D500 in their natural environment:
We also have a Siemens D500 and Bruker D4 and D8 "Bragg-Brentano" (BB)
reflection geometry diffractometers. Although both styles are valued very
highly, if one clicks here one can understand why we
might favour the transmission (Stoe) machine over the more conventional
Our SEM has long since died of old age, but I stll love the images we made
while we had it:

Interests to date include drug polymorphism investigations to establish
crystallographic purity and posible structure of a variety of common-use
drugs. This includes dynamic temperature diffraction and also overlaps with
Prof. Sally Price's group studying this phenomenan from the computational side.
Past work has lead us into
nanopartical studies and the first ever user-data collection from the new
powder diffraction beam-line at the Diamond Light Source.
As an analytical tool, powder diffraction necessarily leads to an eclectic mix
of topics and materials for study. Past examples include the
Roman Sevso Silver,
cladding on telephone cables, asbestos removed from buildings, cow shed
cleaners, human bone/urinary calculi composition and antient Egyptian bronzes.
I shall include information about the other diffraction sets in the department
in due course.
